These can be arranged into a 2? contingency table ( confusion matrix ), conventionally with the test result on the vertical axis and the actual condition on the horizontal axis.
22.
Similarly, in analyses of contingency tables, the chi-squared approximation will be poor for small sample size, and it is preferable to use Fisher's exact test.
23.
The "'grand total "'( i . e . the total number of individuals represented in the contingency table ) is the number in the bottom right corner.
24.
When the total sample size is small, it is necessary to use an appropriate exact test, typically either the binomial test or ( for contingency tables ) Fisher's exact test.
25.
In order to do this one can use information theory concepts, which gain the information only from the distribution of probability, which can be expressed easily from the contingency table by the relative frequencies.
26.
:I think what you have is a contingency table and you want to find if there is a " contingency " ( i . e . non-independence ) between two categorical variables.
27.
This property is sometimes called "'structure conservation "'and directly leads to the geometrical interpretation of contingency tables and the proof of convergence in the seminal paper of Fienberg ( 1970 ).
28.
For very small samples the multinomial test for goodness of fit, and Fisher's exact test for contingency tables, or even Bayesian hypothesis selection are preferable to the " G "-test.
29.
Suppose that there are three possible genotypes at some locus, and we refer to these as aa, Aa and AA . The distribution of genotype counts can be put in a 2 ?3 contingency table.
30.
The support count for each group is a frequency value that can be analyzed in a contingency table where each row represents the truth value of the contrast set and each column variable indicates the group membership frequency.
